Magnetic and transport anomalies and large magnetocaloric effect in cubic R4PtAl (R = Ho and Er)
Kartik K. Iyer, Sudhindra Rayaprol, Ram Kumar +4
We report the electronic properties of R4PtAl (R = Ho, and Er), which contains 3 sites for R, by the measurements of magnetization (ac and dc), heat-capacity, transport, and magnet…
Growth and characterization of high-quality single-crystalline SnTe retaining cubic symmetry down to the lowest temperature studied
Ayanesh Maiti, Ankita Singh, Kartik K. Iyer +1
SnTe, an archetypical topological crystalline insulator, often shows a transition from a highly symmetric cubic phase to a rhombohedral structure at low temperatures. In order to a…
Pressure-induced anomalies in the magnetic transitions of the exotic multiferroic material, Tb2BaNiO5
K. K. Iyer, Ram Kumar, S. Rayaprol +2
We have studied the influence of external pressure up to 1 GPa on the magnetic transitions of the orthorhombic Haldane-spin chain compound Tb2BaNiO5 an exotic multiferroic material…
Anomalies in the temperature evolution of the Dirac states in a topological crystalline insulator SnTe
Ayanesh Maiti, Ram Prakash Pandeya, Bahadur Singh +3
Discovery of topologically protected surface states, believed to be immune to weak disorder and thermal effects, opened up a new avenue to reveal exotic fundamental science and adv…
Competing magnetic interactions and magnetoresistance anomalies in cubic intermetallic compounds, Gd4RhAl and Tb4RhAl, and enhanced magnetocaloric effect for the Tb case
Ram Kumar, Kartik K Iyer, P. L. Paulose +1
We report complex magnetic, magnetoresistance (MR) and magnetocaloric properties of Gd4RhAl and Tb4RhAl forming in the Gd4RhIn type cubic structure. Though the synthesis of the com…
Origin of destruction of multiferroicity in Tb2BaNiO5 by Sr doping and its implications
Ram Kumar, S. Rajput, T. Maitra +6
The orthorhombic Haldane spin chain compound Tb2BaNiO5 (Neel order, TN1= 63 K) has been shown to be an exotic multiferroic system below (TN2) 25 K due to various fascinating featur…
